Calculations of Condenser Performance Using PEPSE. ABSTRACT This paper presents calculation models of a condenser, common to electric power generation stations. Calculations quantify the condenser’s shell pressure as it depends on characteristics of the condenser, such as tube plugging that occurs as the condenser ages. “design mode. Capacity for air-cooled condensers are based on total heat of rejection (THR) at the condenser. THR is equal to net refrigeration at the evaporator (compressor capacity) plus the energy input into the refrigerant by the compressor (heat of compression). The heat of compression will vary depending.
